Specification of Letters Patent.

Patented Jan. 27, 1920.

Application filed February 5, 1915, Serial No. 6,225. Renewed .Tune 17, 1919. Serial No. 304,915.

To all whom it may concern:

Be it known that 1, CHARLES A. Bons'r, a citizen of the United States, and a resident of Brooklyn, Kings county, State of New York, have invented an Improvement in Label-Detaching Devices, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

lhe present invention relates to a label detaching device, the object being to provide an apparatus in which individual labels or the like may be readily detached from a continuous perforated strip.

()ne embodiment of my invention as applied to a hand operated label moistening and serving machine is illustrated in the accompanying drawings, in which Figure l is a side elevation,

Fig. 2 is a front elevation, and,

Figs. 3, 4: and 5 details illustrating d1fferent forms of the label detaching member.

As shown in Fig. 1, a support 1 for a supply of labels may be suitably mounted upon a base 2 in such relation to a moistener 3 that a strip 4.- may be drawn from the supply across the moistener. The support 1, shown in the present instance as a spindle, may have mounted thereon a spider 5, with resilient arms, which press yieldingly against the label supply in such a manner that the strip 4t may be under suitable tension when drawn out by the operator. A separating member 6, having a corrugated cylindrical surface preferably roughened, is conveniently mounted in the frame work 7 of the machine, and positioned to intercept the strip of labels when the latter is deflected from the moistener.

The supply of labels for use in the machine described above may be provided at suitable intervals with perforations 8 between successive labels. In operation, the user draws out a suflicient length of strip across the moistening member to permit an entire label to be rendered adhesive so that when it is severed by being deflected against the separating means, it may be in proper condition to be affixed to a package or other ob'ect.

lDifferent forms of hand operated machines for serving gummed tape in adhesive condition from a continuous imperforated strip are now in common use; but, as ordi narily equ1pped, they are not adapted for serving labels from a perforated strip.

Where attempts have been made to serve labels from a perforated strip in these machines, they have been inoperative for all practical purposes because it was diflicult to make the perforation in the strip coincide each time with the severing edge of the knife blade without considerable delay in operation. Moreover, many labels would be wasted by being severed intermediate the perforations. WVith the construction contemplated in the present invention, however, it is possible for an operator without hesitating to make careful calculations, to draw out a length of strip approximately far enough so that, upon being deflected, it will contact with the separating member in such a manner that the label may be detached accurately along a perforation. Accordingly, the operator is afforded a comparatively wide workable range in withdrawing the strip within which he may detach a whole label accurately at each stroke, be

cause it is unnecessary that the perforation at which the label is to be severed should always meet the separating member along any given transverse line of its periphery as would be the case if said separating member were a knife blade or similar member. While I have shown a corrugated half cylindrical member as the preferred form of detaching device, I also illustrate in Figs. 4 and 5 two modified forms, one being curved and the other having a plurality of faces angularly disposed to each other,

When the improved label detaching device is used to serve adhesive labels, it is understood that the machine may be operated either with a previously gummed strip and a suitable moistener or with an ungummed strip of labels and suitable means for applying an adhesive to one or both sides thereof as the circumstances may demand. In a machine for this purpose, the separating means may be located directly above the moistening member as illustrated in Fig. 1, or may be placed in any suitable position with respect thereto, depending upon the style of the machine in whi h this improvement is to be utilized. It is contemplated that many forms of continuous strip serving machines may be converted into label serving machines by removing the severing device and supplying in its place a sultable separating member involving substantially the construction herein shown and 1. A label serving machine including in' combination a support for a strip of labels, moistening means, and label separating means comprising a strip intercepting memher having a cylindrical surface adapted to provide a fulcrum against which to press the strip adjacent to a line of perforation.

2. A label serving machine including in combination a support for a strip of tape, moistening means, and label separating means adjacent to said moistening means and comprising a member havinga corrugated cylindrical surface.

3. A label serving machine including in combination a support for a strip of tape, moistening means, and strip intercepting means comprising a member having a plurality of angularly disposed surfaces in cylindrical arrangement positioned to intercept the strip transversely, whereby indiyidii'al labels may be separated from the strip along any transverse line of said angularly disposed surfaces.

In testimony whereof, I have signed my name to this specification, in the presence of three subscribing witnesses.
